Hello, just a quick question, I was wondering how a PID, or PI controller could be used in an application involving elevators with a pulley. I can imagine it can be used to control a motor speed, but I can't visualize it working that way. Is it practical to use PID Control in an elevator?

Could someone help me?

Thanks!

Hi Blake,

It is connected to a split phase motor with variable frequency drive for electronic control.

Understanding the value of frequency in PID here -> https://www.youtube.com/watch?v=XfAt6hNV8XM

The electronic control varies according to the load/weight of the elevator that the system automatically adjust with respect to the parameters received.

There are some additional components provided by manufacturers for the efficiency but the concept stays the same.

Hope it helps.

Best,
Neil
